I had a mastectomy 2 months ago and lymph node removal and today I noticed a lump under the armpit. It feels soft and I’m sure it wasn’t there yesterday. Is it usual to have a build up of fluid (seroma) after surgery. Not sure whether to message my breast nurse tomorrow. 

  • Hi RKD welcome to the forum.  Seromas can develop at any point following surgery so there is a strong possibility that this is what you are feeling. If  I was you I would do as you are thinking and get in touch with the breast nurse tomorrow and see if they can have a look at this for you.
